Seedling
7-14 daysYoung corn plants emerge with 2-4 true leaves, growing 3-6 inches tall with narrow, blade-like foliage.
Thin seedlings to proper spacing once plants are 4-6 inches tall. Keep soil consistently moist but not waterlogged. Protect from birds and cutworms with netting or collars.
Vegetative Growth
3-4 weeksPlants develop multiple leaves and establish deep root systems, reaching 2-3 feet tall with visible tillers on some plants.
Apply side dressing of nitrogen fertilizer (or balanced 10-10-10) at V4-V6 stage and again at knee-high stage. Keep weeds controlled. Monitor for pest damage.
Tassel & Silking
1-2 weeksMale flowers (tassels) emerge at the top of plants; female flowers (silks) appear at the ear nodes, becoming visible green structures with silks extending out.
Critical water period—ensure 1-2 inches of water weekly. Avoid nitrogen excess. Hand-pollinate or rely on wind for pollen transfer between plants.
Pollination & Kernel Development
2-3 weeksSilks darken as pollen is transferred; kernels begin to form on the cob and fill out with milk-like fluid, becoming plump and yellow/white.
Maintain consistent soil moisture to prevent kernel abortion. Stop overhead watering once silks fully emerge to reduce disease. Feed with balanced fertilizer if needed.
Maturity & Harvest Ready
2-5 daysEars reach full size with plump kernels that are mostly set; husks turn brown and dried. Kernels release milky fluid when punctured (milk stage) or dent slightly at the crown (soft dough stage).
Check ears every 2-3 days once they reach expected size. Harvest when kernels are in milk stage for peak sweetness. Store harvested ears in cool conditions immediately.

Common Pests
-
Spray Bt (Bacillus thuringiensis) at silk emergence; apply mineral oil to ear tips; hand-pick worms; use pheromone traps for monitoring
-
Plant resistant varieties; apply Bt at whorl and tassel stages; remove and destroy infested plant debris; use insecticidal soap
-
Scout regularly; apply Bt or spinosad; use pheromone traps; remove affected leaves; encourage parasitic wasps
-
Strong water spray to dislodge; insecticidal soap; neem oil; attract natural predators like ladybugs; plant reflective mulches
-
Delay planting until soil warms; apply beneficial nematodes to soil; use row covers until plants establish; avoid planting in cool, wet conditions
Uses
Fresh eating and cooking
CulinaryKandy sweet corn is prized for its exceptional tenderness and sugar content when eaten fresh off the cob, boiled, grilled, or roasted. The bicolor kernels provide both visual appeal and a complex flavor profile combining sweet yellow and creamy white varieties. [source]
Corn kernels for salads and sides
CulinaryFresh kernels can be cut from the cob and added to salads, salsas, succotash, and grain bowls. The kernels retain excellent texture when lightly cooked or raw. [source]
Ornamental garden feature
HouseholdKandy's attractive appearance with mixed yellow and white kernels makes it visually interesting in the garden, adding height and structure to vegetable beds. [source]
Freezing and preservation
CulinaryKandy corn freezes well when blanched and cooled, providing home gardeners with a way to preserve the summer harvest for use throughout the year in soups, stews, and side dishes. [source]
Wildlife food source
WildlifeMature corn plants provide food and shelter for various pollinators and beneficial insects, and leftover cobs and stalks can support wildlife in fall and winter. [source]
Harvest Tips
Harvest when ears are in the milk stage (kernels release milky fluid when punctured with a fingernail), typically 20 days after silking. Pull ears downward and twist sharply. Kandy is ready when kernels are plump and tender but before they become starchy. Harvest in early morning for maximum sweetness and store in refrigerator immediately to preserve sugar content; use within 2-3 days for peak flavor.
Fun Facts
- 🌱 Kandy corn is a hybrid variety, meaning it's created by cross-pollinating two specific parent plants to achieve the bicolor trait and superior sweetness—seeds from Kandy ears won't produce true-to-type plants, so gardeners must purchase new seed each year.
- 🌱 The kernels contain higher sugar content and lower starch compared to field corn, which is why sweet corn varieties taste so much better fresh; the sugar begins converting to starch within hours of harvest, which is why corn tastes sweetest when eaten very soon after picking.
- 🌱 Corn is a heavy feeder and depletes soil nitrogen quickly, which is why Indigenous peoples traditionally planted corn, beans, and squash together in the 'Three Sisters' polyculture—the beans fix nitrogen back into the soil while the squash provides ground cover and moisture retention.
